First off, it’s the ebb current that’s the faster current, with speeds up to 4 kts. The flood is about a knot slower. Moreover, this issue exists only in the immediate vicinity of the Atlantic Boulevard bridge. Looking at the chart, the opening between the bits of land to the north of the bridge taper down, but open quickly to the south. We recently passed through the area with a 3 kt flood current and had little trouble under the bridge and only moderate turbulence south of the bridge. The St. Johns River crossing, by comparison, was harder, with strong cross current and turbulence.

Try to hit this bridge at slack tide. Otherwise you will be facing a swift current (4+ kts) which will test your nerves and
helmsmanship passing under the bridge.

Revised FDOT drawings for this particular bridge confirm that one corner of this bridge is at 63 feet MHW. Due to the slope of this bridge this is the lowest corner. The other three points of the fender measure at 65 ft MHW and the bridge has 67 ft at the center.
